Generally, having prior or pending immigration applications is not a problem. However, if you want to file for a nonimmigrant visa AFTER you file for a green card, you may have a problem showing that you intend to return to your home country. Also, if you’ve filed or will file other applications, you want to make sure that they are all consistent. If you see a mistake on a past application, don’t change your current application to fit the mistake–figure out with your experienced immigration attorney if you can safely bring the mistake to the attention of USCIS when you file a new application with the updated answer. Finally, make sure to share a copy of all your prior applications with your new attorney. If you don’t have copies of them, request them with a Freedom of Information Act (FOIA) Request.
